What I'm using.
Makerbot Mini using the default Standard Makerbot Profile
Rafts - On (always on by default with the Mini)
Supports - Off
Infill - 10%
Number of Shells - 2
Layer Height - 0.20MM
Makerbot Natural Color PLA
Here was my first test.
Fine Positive Space Features Performance
I'm going to assign it a 2 out of 5... even though it jammed on me and I had to restart (I think my extruder is failing at this point and my mini is about 2 weeks old... going to try a few more test prints and see if it continues to jam)
